The two types of peppered moths are the light-colored form called typica and the dark-colored form called carbonaria. These moths became famous for illustrating natural selection during the Industrial Revolution in England.

About 98% of peppered moths were dark by 1900 due to industrial pollution causing trees to darken, making dark moths more camouflaged and increasing their survival rates.
Peppered moths primarily feed on nectar from flowers when they are in their adult stage. In their caterpillar stage, they feed on the leaves of trees such as oak, birch, and elm. They also consume algae, lichens, and fungi found on tree bark.
Peppered moths get their name from the pepper-like speckles on their wings, which resemble the appearance of peppercorns. This pattern helps them blend in with tree bark, providing camouflage and protection against predators. The moths are commonly found in both light-colored and dark-colored forms, known as the light and dark morphs.
The example of peppered moths is not really different from Darwin's theory, it is the same concept. The only difference is that peppered moths live in the same habitat, where as Darwin's finches live in different habitats, which drove the evolution of their different beak shapes. The peppered moths have adapted to blend into their environment so they're not as easily caught.

Peppered moths have Camouflage and Mimicry, the use of Camouflage is to hide from predators.
Peppered moths are so named for their appearance with their many black spots. The larvae thrive by eating the leaves from a variety of trees like the oak tree.

Charles Darwin did not study peppered moths. The study of peppered moths and their evolution in response to industrialization was done by British biologist Bernard Kettlewell in the mid-20th century, not by Darwin. Kettlewell's research on peppered moths played a key role in illustrating natural selection in action.
